  Structural Analysis of Chiral Dopants in Nematic Systems by Example of Ether-Ester-Substituted 1,4:3,6-Dianhydrohexitols

  摘要：

  Series of ether-ester-substituted 1,4:3,6-dianhydrohexitols were synthesized and studied as chiral dopants to nematics as compositions with 4 '-pentyl-4-cyanobiphenyl. The most helical twisting power was found for bis-esters. Lesser values were found for mixed ether-esters with certain configuration. Other ethers and ether-esters revealed noticeably smaller values. Supramolecular peculiarities of such systems and their role in helical twisting are discussed.

  The present invention relates to a marking of polymeric liquid crystal material having determined optical characteristics allowing its authentication and reading by a machine and its authentication by the human eye. The marking is applied onto an item, good or article by a variable information printing process. The marking is in the form of indicia representing a unique code which allows for an easy authentication by the human eye and a secure tracking and tracing of the marked item, good or article throughout is life cycle.
